ISAAC D'. FINO/H, OF MEMPHIS, TENNESSEE.

WAGON-AXLE.

SPECIFICATION forming part of Letters Patent No. 263,328, dated August 29, 1882.

Application filed January 2B, 1882. (No model.)

To all whom fit may concern:

Be 1t known that I, ISAAC D. FINOH, a citizen of the United States, residing at Memphis,

ot' the skein.

in the county of Shelby and State of Tennessee, have invented a new and useful Improvement in Wagon-Axles, of which the following is a specication.

My invention relates to wagon-axles combined of wrought-iron, cast-iron, and Wood.

The objects of my invention are, rst, to strengthen the Wagon-axle in which a skein is used at the collar or shoulder of the skein, which has been heretofore its weakest point; second, to combine the three materials named in such form as to insure increased durability; and, third, to reduce the expense cfa combined axle by nsingonly such aproportion of wroughtlron as will insure the requisite strength and durability. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure lis a general outside view of the combination. Fig.2isahorizontalsectional View of the end of the combinedaxle, and Fig. 3 is a view showing a vertical section of the end of the combined axle.

Similarletters refer to similar parts throughout the several views.

E is the wooden axle-tree. F is the cast-iron skein. Gr represents the wrought-iron part of the axle. His the core-print. D D are anges at the bottom ofthe skein F. K is the collar S is an opening on the top of the base of the skein, in which the end ofthe wooden axle-tree rests. J J are depressions in the edge of the wrought'iron part G of the axle. O is the clip. f

To enable others to make use of my invention, I will describe in detail the manner of its construction.

I use a iiat bar of wrou-ghtiron,'G, which may be two inches wide and iive-eighths of an inch thick for a skein, F, that is three inches in diameter at the base. I forge depressions J J on the edges of this wrought-iron bar Gr at each end, for the purpose of enabling the cast-iron skein F to be cast around the end of the bar Gr, so as to fasten them securely and solidly together, while at the same time leaving a large portion of the cast-iron skein F hollow. In casting the skein F, I extend the Vflat bar G into the cast-iron seven inches from the base of the skein, and one and three-fourths inch beyond or outside of the collar K, by

which means Istrengthen the axle at the point of the collar K, which has heretofore been the weakest point in all wagon-axles. I leave an opening, S, on the top of the base ot' the skein F two and one-fourth inches wide and two inches deep, extending to within threefourths of an inch of the collar K and downward to Within ve-eighths of an inch ofthe at bar G. The cast skein F is three-fourths of an inch thick on the top of the opening or core-print H, inside the collar K, thus furnishing a shoulder or bearing for the square end of the wooden axle E to rest against on its upper side. This Wooden axle E being fitted exactly into the opening S, it has also on its lower side an end bearing or shoulder ve-eighths of an inch thick against the end ot` the cast skein F and on the top ofthe dat bar G. I secure and hold all these parts thus arranged firmly together by means of a clip, O, and a clip-bar resting between the flanges D D, and also by bolts such as are ordinarily used in wagon-axles.

Iam aware thatprior to myinvention wroughtiron bars have been used in wagon-axles, and that combinations of wrought-iron, cast-iron, and wood have been employed in such axles. I therefore do not claim such a combination generally or broadly; but

What I do claim as myinvention,an d desire to secure by Letters Patent, is-

1. The combination of hollow cast-iron skein F and the wrought-iron axle-bar G, united together in the manner shown and described.

2. The combination of the wrought-iron axlebar Gr with hollowr cast-iron skein F and the wooden axle-tree E, having end bearingtitting in the openingSof the skein, substantially as shown and described.

3. Thehollowthimble-skein having the opening S and flanges D D on the bottom of the same, in combination with the dat bar G, having depressions J J, the wooden axle E, and clip O,all united and combined as set forth.
